The rear panel 16 has a front surface 16 a and a rear surface 16 b which face opposite directions, wherein the front surface 16 a of the rear panel 16 faces the outlet portion 142. The rear panel 16 has a receiving groove 162, an engaging track 164, and a projection 166, wherein the receiving groove 162 disposed on the rear surface 16 b and is adapted to be engaged with the liquid storage tank 20. The engaging track 164 is a first engaging portion of the current embodiment. The engaging track 164 extends along a first predetermined direction D1 and is formed on a groove surface 162 a of the receiving groove 162, wherein the first predetermined direction D1 is a longitudinal direction of the shower body 10. As shown in FIG. 4, the engaging track 164 has a narrow section 164 a and a wide section 164 b in a direction away from the groove surface 162 a of the receiving groove 162, wherein the narrow section 164 a is connected to the groove surface 162 a. In the current embodiment, a cross-section contour of the engaging track 164 is, but not limited to T-shaped. In other embodiments, the cross-section contour of the engaging track 164 could be other shapes, such as in the shape of an arrow or a circle arc, as long as a width of the wide section is greater than a width of the narrow section in a third predetermined direction D3 defined on the cross-section contour.

As shown in FIG. 9, the projection 166 protrudes from the front surface 16 a of the rear panel 16 along a second predetermined direction D2, wherein the second predetermined direction D2 is orthogonal to both of the first predetermined direction D1 and the third predetermined direction D3. The projection 166 has an engaging hole 166 a penetrating through the rear surface 16 b from an end of the projection 166 to the rear surface 16 b of the rear panel 16, that is, an axial direction of the engaging hole 166 a is parallel to the second predetermined direction D2, wherein a diameter of the engaging hole 166 a at the projection 166 is large than a diameter of the engaging hole 166 a at the rear surface 16 b, thereby forming a shoulder 166 b in the engaging hole 166 a. A positioning member 18 is disposed in the engaged hole 166 a, wherein the positioning member 18 includes a positioning protrusion 182 and a spring 184. A side of the positioning protrusion 182 is connected to an end of the spring 184, and another side of the positioning protrusion 182 abuts against the shoulder 166 b and partially protrudes from the rear surface 16 b of the rear panel 16. Another end of the spring 184 that is not connected to the positioning protrusion 182 is engaged with the front panel 14.

The liquid storage tank 20 has a box body 22, a pump tube 24, a cap body 26 and a pressing member 28, wherein the box body 22 has a receiving space A therein, and the receiving space A communicates with an outside via an opening 22 a, so that liquid solutions such as shampoo or shower gel could be received in the receiving space A through the opening 22 a. As shown in FIG. 3 and FIG. 4, a side surface of the box body 22 facing the shower body 10 has an engaging groove 222 corresponding to the engaging track 164 and a positioning hole 224 corresponding to the positioning member 18. The engaging groove 222 is a second engaging portion of the current embodiment. The engaging groove 222 has a first section 222 a and a second section 222 b, wherein a contour of the first section 222 a and a contour of the second section 222 b are respectively complementary to a contour of the narrow section 164 a and a contour of the wide section 164 b. That is, a width of the first section 222 a is smaller than a width of the second section 222 b in the third predetermined direction D3. The positioning hole 224 is adapted to position a position of the positioning member 18 in the first predetermined direction D1. In addition, as shown in FIG. 8, the box body has at least one supporting member 226. In the current embodiment, the box body 22 has a plurality of the supporting member 226 laterally abutting against the pump tube 24 in the receiving space A, along the second predetermined direction, thereby the pump tube 24 could be firmly disposed in the box body 22.

The cap body 26 of the liquid storage tank 20 enclose the opening 22 a and is connected to a peripheral edge of the opening 22 a. The cap body 26 fits around the pump tube 24, thereby the pump tube 24 is partially exposed outside the cap body 26. The pressing member 28 is adapted to press against a part of the pump tube 24 exposed outside the cap body 26, and has a liquid outlet 28 a communicating with the pump tube 24 via a connecting pipe 29, wherein the connecting pipe 29 is a curved pipe with a reentrant angle of 90 degrees, and has a first port 29 a and a second port 29 b. The first port 29 a is connected to the liquid outlet 28 a, and the second port 29 b is connected to the pump tube 24, so that the liquid outlet 28 a communicates with the receiving space A.

The engaging groove 222 of the liquid storage tank 20 could move along the first predetermined direction D1 to be sleeved or disengaged from the engaging track 164 of the shower body 10, so that the liquid storage tank 20 could be detachably engaged with the shower body 10. It is worth mentioning that when the engaging track 164 of the shower body 10 is not completely located in the engaging groove 222 of the liquid storage tank 20, the positioning protrusion 182 is pressed by a side surface of the liquid storage tank 20, to compress the spring 184 to be completely located in the engaging hole 166 a. Until the engaging track 164 of the shower body 10 is completely located in the engaging groove 222 of the liquid storage tank 20, and the positioning hole 224 of the liquid storage tank 20 faces the engaging hole 166 a of the shower body 10, at this time, the spring 184 restores to its natural length by an elastic forced generated by the spring 184, wherein the elastic forced generated by the spring 184 urges the positioning protrusion 182 to moves along the second predetermined direction D2 and enter the positioning hole 224. In this way, the positioning member 18 restricts the liquid storage tank 20 from changing a position in the first predetermined direction D1, thereby preventing the liquid storage tank 20 from accidentally sliding down. As shown in FIG. 4, when the liquid storage tank 20 is pushed by an external force F toward the second predetermined direction D2, the wide section 164 b of the engaging track 164 could be stuck in the second section 222 b of the engaging groove 222 to prevent the liquid storage tank 20 from being detached along the second predetermined direction D2.

When a user is about to press out the cleaning solution in the receiving space A, press the pressing member 28, and the cleaning solution will flow out of the liquid outlet 28 a by passing through the pump tube 24 and the connecting pipe 29. More specifically, in the current embodiment, the liquid outlet 28 a faces a direction away from an outlet direction of the outlet portion. In this way, when the liquid outlet 28 a supplies the cleaning solution, the cleaning solution would not be directly flushed away by water flowing from the outlet portion 142, and the user would not be spattered by the water from the outlet portion 142. However, in other embodiments, the liquid outlet 28 a could be disposed to face other directions.

A handheld shower 100A of a second embodiment is illustrated in FIG. 10. In the current embodiment, a first engaging portion of a first liquid storage tank 20A is an engaging track 222A, and a second engaging portion of a shower body 10A is an engaging groove 164A, and the engaging track 222A could be inserted into the engaging groove 164A. In addition, a positioning member 18A is disposed on the shower body 10A, and the liquid storage tank 20A has a positioning hole 224A. The aforementioned structural design can also achieve the same restricting effect as the first embodiment.

As illustrated in FIG. 11 to FIG. 19, a handheld shower 200 according to a third embodiment of the present invention includes a shower body 30 and a liquid storage tank 44. The shower body 30 has an inlet channel 32 and an outlet portion 34. The liquid storage tank 44 is detachably engaged with the shower body 30.

More specifically, in a longitudinal axial direction of the shower body 30, the shower body 30 has a first end 36 and a second end 38 which are opposite, wherein the first end 36 has an inlet portion 362 which communicates with the inlet channel 32. The shower body 30 has a receiving groove 40 which is recessed along the longitudinal axial direction of the shower body 30 and is located at another side of the shower body 30 which is away from a side disposed with the outlet portion 34. A mouth 402 of the receiving groove 40 is formed at the second end 38 of the shower body 30. The liquid storage tank 44 could be inserted through the mouth 402 to the receiving groove 40. A slot 42 is formed on the another side of the shower body 30 which is away from the side disposed with the outlet portion 34. In the current embodiment, the slot 42 is opposite to the outlet portion 34. The slot 42 communicates with the receiving groove 40 and the mouth 402.

A first positioning portion 404 is disposed on a wall of the receiving groove 40 and is near to a bottom end of the slot 42. A box body 46 of the liquid storage tank 44 has a second positioning portion 462 which is located at a bottom portion of the box body 46. In the current embodiment, the first positioning portion 404 includes, but not limited to, at least one recess, and the second positioning portion 462 includes, but not limited to, at least one protrusion. Alternatively, the first positioning portion 404 could include at least one protrusion, and the second positioning portion 462 could include at least one recess.

After the liquid storage tank 44 is engaged with the receiving groove 40, a part of the box body 46 of the liquid storage tank 44 is exposed outside through the slot, and the first positioning portion 404 is complementarily engaged with the second positioning portion 462 to position the liquid storage tank 44, thereby preventing the liquid storage tank 44 from disengaging from the receiving groove 40.

When the user wants to take off the liquid storage tank 44, the user could simply push the part of the box body 46 of the liquid storage tank 44 which is exposed outside through the slot 42 to move toward the mouth 402 of the receiving groove 40 to disengage the liquid storage tank 44 from the shower body 30. Additionally, when the box body 46 is transparent or translucent, a volume of a cleaning solution stored in the box body 46 is visible through the slot 42. In the current embodiment, an opening of a liquid outlet 482 a of a pressing member 48 of the liquid storage tank 44 faces toward an outlet direction of the outlet portion 34.

For preventing a cleaning solution provided through the liquid outlet 482 from being flushed away by a large volume of water, in the current embodiment, the handheld shower 200 further includes a valve 50 for restricting flow. The valve 50 for restricting flow is adapted to limit a volume of water flow passing through the inlet channel 32, so that a water flow outputted through the outlet portion 34 could be switched between a first flowing mode and a second flowing mode, wherein an outputted water volume of the second flowing mode is less than that of the first flowing mode. In other words, the first flowing mode could output a great amount of water, and the second flowing mode could output a small amount of water or stop outputting water. Preferably, the second flowing mode could output a small amount of water to avoid a flexible hose connected to the inlet portion 362 to burst due to excessive water pressure.

As illustrated in FIG. 16 to FIG. 19, the valve 50 for restricting flow is disposed in the shower body 30 and is located between the receiving groove 40 and the first end 36. The valve 50 for restricting flow includes an operating member 52 and a valve core 54. The operating member 52 has a button 522 which is located at the another side of the shower body 30 which is away from the side disposed with the outlet portion 34 and is adapted to be pressed by the user. In the current embodiment, the button 552 is opposite to the outlet portion 34. The operating member 52 could be operated to move between a first position P1 as shown in FIG. 17 and a second position P2 as shown in FIG. 19. The inlet channel 32 has a valve opening 32 a which is located between the outlet portion 34 and the inlet portion 362. The valve core 54 is located at a position corresponding to the valve opening 32 a. When the button 522 is not pressed, the operating member 52 is located at the first position P1 and drives the valve core 54 to disengage from the valve opening 32 a of the inlet channel 32. At this time, water flowing through the valve opening 32 a does not be blocked by the valve core 54, so that the outlet portion 34 outputs water in the first flowing mode, namely outputting a large volume of water. When the button 522 is pressed, the operating member 52 is located at the second position P2 and drives the valve core 54 to block the valve opening 32 a of the inlet channel 32. At this time, the water could flow through a gap between the valve core 54 and the valve opening 32 a, so that the outlet portion 34 outputs water in the second flowing mode, namely outputting a small volume of water, thereby pausing water flow outputted through the outlet portion 34. In another embodiment, when the operating member 52 is located at the second position P2, there is no gap between the valve core 54 and the valve opening 32 a, thereby temporarily stopping water flow outputted through the outlet portion 34.

For example, as illustrated in FIG. 18 and FIG. 19, when the user wants to use the cleaning solution, the user could press the button 522 first to allow the operating member 52 to stay at the second position P2 and to make the valve core 54 block the valve opening 32 a of the inlet channel 32, thereby making the outlet portion 34 output a small amount of water. Then, press the pressing member 48 to make the cleaning solution flow out through the liquid outlet 482. At this time, the small amount of water outputted through the outlet portion 34 could dilute the cleaning solution, so that the user could easily apply the cleaning solution. After that, when the user wants to shower, the user could press the button 522 to allow the operating member 52 to return to the first position P1, thereby making the outlet portion 34 output a great amount of water for the user to shower.

The valve 50 of the current embodiment for restricting flow passing through the inlet channel 32 could be applied to the first embodiment or the second embodiment.

In summary, the liquid storage tank is engaged with the shower body in a detachable manner, so that the user not only has no need to carry bottles when traveling or on business trips, but also could carry the handheld shower that the user familiar with, which could improve the user's shower experience and quality of life when going out In addition, the handheld shower of the present invention could be easily assembled and detached, which is very convenient, and multiple liquid storage boxes could be carried for replacement during a long-distance trip.
